I have two friends that never had a second child and it was connected with their husbands who also had busy jobs and just didn't think that childcare should impinge on their careers, even though both women also had big careers.
It was interesting at the time (19-20 years ago) as both women are quite direct and when asked about having a second, as people invariably feel the need to🙄, they answered that their husbands played no part in childcare and they wouldn't be having another.....a real conversation killer😁.
This happened at numerous extended family gatherings.
One MIL at a certain point became very upset as she felt it was private family business being hung out in public.
Both marriages ended within 5 years... as unsurprisingly my friends said they lost ALL interest in them sexually as it became clear that they didn't have their backs.
Both men aren't bad men but admitted years later to being regretful of their selfishness and have been good fathers since, possibly fuelled a bit by guilt.
They have been better fathers second time round, a decade later.
Neither women remarried but both have long term partners that they don't live with. "Together but apart" has been their very successful arrangement.
I cannot understand the continuing to have children with a selfish man and somehow expecting them to improve.
It's simply far too big a risk, yet so many women take it.
These same women are then surprised that their libido has vanished around this time.
Of course it vanishes.
Raising small children is shattering and women feel touched out.
The very last thing many of them want is to be intimate with the lazy arse next to them in the bed, whom has let them down so badly by refusing to share the load of children they made together.
The betrayal and resentment is corrosive to desire and love.
Sex involves trust at its core.
Why would you want to being having sex with someone who has comprehensively broken your trust and let you and your children down?
And yet men and women often still don't make the connection, that how those early hard years play out, is often a huge barometer of the future health, sexual and otherwise, of a relationship long term🤷🏻♀️.
